Why are all my apps crashing all the time?

For whatever reason, this problem began this morning. I have not installed any new apps in over a week, and have not had problems like this before.

Apps consistently crash, and I keep getting poppup alerts about it which makes any kind of navigation next to impossible. Most consistently, I get "com/google.process.gapps" stopping, although more or less every app pops up at some point. This is not even an app that appears in my app manager in settings, so I can not clear the cache on it or disable and reenable it.

I can't even get to the google play store without it crashing, so cannot get a cashe clearer.

I have tried manually going through the apps, clearing the cashes, but it is impossible to navigate without a ton of popups preventing me from proceeding.

If you manage to access the battery stats check if there's an app using much more battery than expected. If so, force stop it and see if that helps.
If this doesn't help try to boot your phone in safe mode. If the problem doesn't appear it means that there's an app going wild.
